Why does the CDC recommend that routine, opt-out HIV screening start with 13-year-olds?
Research indicates that a significant percentage of teens are sexually active, which automatically puts them at risk for contracting STDs, including HIV. A 2007 CDC survey found that 47% of students in grades 9-12 reported having had sexual intercourse at least once, and 37% of sexually active students did not use a condom during their last act of sexual intercourse. Routine HIV screening would also allow many teens to get tested for HIV, without having to disclose their sexual activity to their parents.
